SELF-CLOSING FAUCET.

Application filed May 18, ISFS.

" (33323013 forming part of Letters Patent No. 325,412, dated September 1, 1885.

(X0 model.)

To all whom it may concern:

Be itknown that I, ANDREW J. HUMAN, of the city, county, and State of New York, have invented a new and Improved Self-Closing Faucet, of which the following is a full, clear, and exact description.

My invention relates to faucets adapted for discharging fluids, and has for its object to simplify the construction and promote the durability and more convenient operation of devices of this character.

The invention consists in particular constructions and combinations of parts of the faucet, all' as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part oft-his specification, in which similarletters of refcrenceindicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improved faucet with the valve closed. Fig. 2 is a like view with the valve open, and Fig. 3 is a back end view of the faucet,

The letter A indicates the body of the faucet, which preferably has a nozzle, a, projecting at aright angle from it, and in the nozzle and body is formed the annular water way or outlet B, in front of the plug-valve O, which is fitted in a bore of the body somewhat larger than the water-way B, so that the forward end, 0, of the valve, which preferably is beveled, may close tightly to a shoulder, 11, at the inner end of the outlet 13, which shoulder forms the valve-seat, and directly behind the shoulder b the bore of the body A is enlarged for a little distance along the body to form around the valve 0 the Z1I1I1Hl8I',OlltX11b6l D.

The valve 0 is a hollow plug closed at the forward end, 0, which forms the valve-face, and the valve has a stern, E, which passes through theend of the body A and receives a push-button, F. Directly back of the face 0 the tubular body of the valve is provided with a series of side apertures, G, which commu nicate with the chamber 1), so that when the button F is pushed back to throw the valve away from the shoulder or seat 2) the water or other fluid will flow into the interior of the valve and escape through the apertures G into the chamber D, and thence between the face 0 and seat I) of the valve through the waterway B, whence it discharges as long as the valve remains open.

The sum of the areas of all the apertures G is less than the area of opening which the valve has when fully pushed back by the button F; hence when the valve is open the water or other fluid passing through the apertures G will pass freely from the faucet withoutexerting back-pressure on the head of the valve, and so that the fluid-pressure always will act on the inside of the closed forward end or head of the valve to close the valve to its seat and cut off the flow of the fluid when the pressure on the button F is relaxed, or when the valve is not retained open by the pin and cam device presently described.

The plug-valve C is cylindrical, and may be turned axially by turning the button F, and at its back end the valve carries rigidly a pin, H, which preferably is fitted in opposite walls of the valve, and has a projecting end, 71, adapted to travel over the extreme inner end of the body A, which is shaped as a helical or spiral curve, forming a face cam, I, which terminates at its highest point at a shoulder,

It is evident that when the end h of pin H rests in front of the shoulder 43 of earn 1, as in Figs. 1 and 3, the valve C may close, and may be opened by pushing in the button F; and it it should be desired to retain the valve open more or less at any time without holding the butt-on F back, it only is necessary to turn the valve axially, so the end h of pin 1-1 will ride up the cam I, and the pressure of the fluid on the valve will hold the pin against the cam at any place it may be set by turning the button so that the continued discharge from the faucet may be regulated at will; and to allow the Valve to close it only is necessary to turn the valve either way until the end It or pin H will stand in front of or against the cam-shoulder t, as will readily be understood.

I show the inner end of the faucet-body A formed as a threaded nipple, a, which may be screwed into a vessel, as at J in dotted lines, from which the fluid is to be drawn; but the faucet may have any style of fastening or connection with a vessel or pipe as circumstances may require.

The faucet may cheaply be made, and is durable, as it has butfew and simple parts, which are not liable to get out of order. Furthermore, no special packing is required, but the valve and seat are composed wholly of metal, thus dispensing with perishable leather, rubber, or other packing; and it will be seen that the fluid enters the interior of the valve at its back end and passes along inside the valve to the outlets G, and thence to the pas sage B, when the valve is opened.

Having thus fully described my invention, I claim as new and desire to secure by Letters 1ate11tl. A self-closing faucet consisting of a main port-ion or body having a stationary valveseat and three interior chambers of different diameters, but all having the same center line, ahollow plug-valve having side openings and closed forward end, and a manipulating device that passes through one 01' the chambers formed in the main portion or body ofthe valve, substantially as set forth.

2. A self-closing faucet consisting of amain portion or body having a beveled stationary valve-seat and three interior chambers of different diameters, but all having the same center line, a hollow plug-valve having side openings and closed forward end, and a manipulating device secured to the closed end of the plugwalve and passing through one of the chambers formed in the main portion or body of the valve, substantially as set forth.

turned axially and fitted in the body A, and

having a closed forward end, and apertures G, communicating wit-h chamber D, and provided with a pin, 71, and means, substantially as described, for turning the valve to open it, substantially as herein set forth.

5. A faucet comprising a body A, having outlet B, chamber D, valve seat I), and facecam I, and a hollow cylindrical plug-valve, O, fitted to body A, and having a closed forward end, and provided with side apertures, G. communicating with chamber D, and also with a pin, h, and also with a stem, E, extended through the body A and provided With a head or button, F, substantially as herein set forth.
